Full explanation of the simulation algorithm used to simulate the results in this thesis is also given. The simulation result of the last design shows that a concentrated broad solar spectrum of up to 500 nm can be achieved by utilizing two diffractive gratings. One blazed transmission grating located on the top and another blazed reflection grating placed below bottom surfaces of the wedge prism. The gratings diffract the incident light guiding it into the wedge prism. The guided light is then projected onto the solar module located at the end face of the prism. With this coupling mechanism, the concentrator’s length-to-thickness ratio can exceed 7, the maximum concentration ratio exceeds 3.7, and angular tolerance can reach ±53° and ±9° in the two planes of incidence. In addition, the polarization dependence, as a property of the one-dimensional diffractive grating, is suppressed.
